Benefits of technology

[0005] Accordingly, the general object of the present invention is to provide artificial turf in which the tufted fibers are more securely held in place.
[0007] Another object is to provide artificial turf that has a primary backing that facilitates tuft bind.
[0008] Another object is to provide artificial turf which provides better lateral support for seaming.
[0009] Another object is to provide artificial turf that has a primary backing that facilitates seaming.
[0010] Another object is to provide artificial turf which has increased dimensional stability.

Problems solved by technology

However, turf systems known in the prior art still have problems with tuft bind, do not provide certain desired dimensional stability and biomechanical properties, and do not have long-lasting seaming strength.

Embodiment Construction

[0030] At the outset, it should be clearly understood that like reference numerals are intended to identify the same structural elements, portions or surfaces consistently throughout the several drawing figures, as such elements, portions or surfaces may be further described or explained by the entire written specification, of which this detailed description is an integral part. Unless otherwise indicated, the drawings are intended to be read (e.g., cross-hatching, arrangement of parts, proportion, degree, etc.) together with the specification, and are to be considered a portion of the entire written description of this invention. As used in the following description, the terms “horizontal”, “vertical”, “left”, “right”, “up” and “down”, as well as adjectival and adverbial derivatives thereof (e.g., “horizontally”, “rightwardly”, “upwardly”, etc.), simply refer to the orientation of the illustrated structure as the particular drawing figure faces the reader. Similarly, the terms “inw...

Abstract

Artificial turf (15) comprising a primary backing (16) having a first side (52) and a second side (53) and including a first backing layer (23), a second backing layer (24), a third backing layer (25) and a fourth backing layer (26), a plurality of fibers (19) sewn or tufted through the primary backing, and a secondary backing on the second side of the primary backing. The first layer may facilitate tufting, the second layer may facilitate dimensional stability, the third layer may facilitate tufted bind and the fourth layer may facilitate seam strength. The fibers may form upstanding ribbons (17) on the first side of the primary backing and the turf may further comprise an infill layer (20) disposed between the ribbons. The fibers may form a plurality of back stitches (27) on the second side of the primary backing and the secondary backing may cover the back stitches and lock in the fibers.

Description

TECHNICAL FIELD [0001] The present invention relates generally to the field of artificial turf, and more particularly to artificial turf having an improved primary backing that includes multiple primary backing layers. BACKGROUND ART [0002] In the past, artificial turf has been made by tufting synthetic grass fibers through a primary backing. The primary backing has generally been made of a layer of polypropylene material, either woven or non-woven, through which the artificial turf fibers are tufted. Typically, after the artificial fibers are tufted through the primary backing, the underside of the backing is coated with an adhesive to help secure the tufted fibers. Panels of the turf are then joined together to cover the desired area. However, turf systems known in the prior art still have problems with tuft bind, do not provide certain desired dimensional stability and biomechanical properties, and do not have long-lasting seaming strength. [0003] Hence, it would be beneficial to...
